Bandai Namco Entertainment has just launched its first Gundam-themed competitive FPS on PC and console, Gundam Evolution. However, not all Mobile Suit pilots are happy. The majority of players seem to report that they encountered an Error Code 503 message that won’t let them boot up the game. If you are one of many players affected by this issue, here is how you can fix Error Code 503 in Gundam Evolution.

Gundam Evolution – Fix Error Code 503

There are two reasons behind Gundam Evolution Error Code 503 message, and you actually do not need to do anything to fix the issue. First, you might have encountered it before the game was officially released. Gundam Evolution launched on September 21 at 7 PM PDT or 10 PM EDT on PC, and the Xbox and PlayStation versions will follow at a later date on November 30. However, in the case of the Steam version, the game was available to be preloaded a day before, although we can assume that Bandai Namco will do the same when it releases on consoles. That means the files were able to be downloaded, but the servers are not accessible yet.

You will also see Error Code 503 when Gundam Evolution is having server maintenance. On the Steam page, in order to fix some connection issues, it says that the game’s server will be unavailable for a while — from 22 September 2022 from 11 PM to 23 September 1 AM PDT. Be aware that the end time for this maintenance may differ depending on the severity of the issue.

Interestingly, there is a way to bypass server maintenance. All you need to do is:

  • Go to the Main Menu.
  • Look at the top-right corner of your screen and click on the box next to the Matching Area text.
  • Doing this will let you change the regional server. Just go into servers that are available to be played.
  • While progress and unlocks are shared between servers, of course, changing servers means you should expect fluctuating lags and pings the further away your location from the server.

Nevertheless, if you are still having problems with Error Code 503 in Gundam Evolution outside of server maintenance periods, you might want to contact the official Gundam Evolution Support forums to fix the issue.

Gundam Evolution is now available on PC via Steam. The console version will be released later for PS5, PS4, Xbox One, and Xbox Series X|S on November 30, 2022.
